What does the UPS lithium-ion battery production process mean?

The production process of UPS lithium-ion battery is different depending on the manufacturer of the lithium-ion battery. However, due to the communication, the production process of important lithium-ion batteries is basically the same. Generally, there are: ingredients, coating, rolling, and cutting. , Slitting, welding tabs, winding, packaging, baking, liquid injection, forming, forming, sub-volume testing and other processes. In the necessary steps for the production process of UPS lithium-ion batteries, five aspects should be paid attention to from the selection and speculation of the volumetric detection after forming. 1. Improve the physical and chemical layout of the positive and negative active materials, which is the basic of the production process of lithium-ion batteries. Link; 2. The high bonding strength of the electrode coating is conducive to reducing the rate of decrease in cycle capacity, which is the most technical process in the production process of lithium-ion batteries; 3. The optimization of the electrolyte composition, the production process of UPS lithium-ion batteries The requirement of the electrolyte is to maintain the capacity and prolong the life of the battery; 4. After the preparation of the battery material, the production process of the lithium ion battery enters the assembly process. At this time, pay attention to the capacity of the negative electrode slightly larger than the capacity of the positive electrode; For national standards, it is advisable to charge at a low rate, generally 0.2C. The time of each step in the production process of lithium-ion batteries is different. In general, the time for ingredients, baking, and formation is long, ranging from about 10 hours to two days and two nights; other processes are relatively fast, with an average of 5, 6 Hours. The entire production process of lithium-ion batteries takes 15 days. In general, the following proportions should be paid attention to in the process and manufacturing stage: the compaction density of the pole unilateral and the pole piece, the excess rate of the negative electrode, the formulation process, the combination of the electrolyte and the positive and negative electrodes.
